Abstract (en)

[origin: WO2020053559A1] A single coated conductor for an overhead power transmission or distribution line is provided comprising one or more electrical conductors (400) and a first coating (401) provided on at least a portion of the one or more electrical conductors (400). The first coating (401) comprises: (i) an inorganic binder comprising an alkali metal silicate; (ii) a polymerisation agent comprising nanosilica ("nS") or colloidal silica (SiO2); and (iii) a photocatalytic agent, wherein the photocatalytic agent comprises ≥ 70 wt% anatase titanium dioxide (TiO2) having an average particle size ("aps") ≤ 100 nm. The first coating (401) has an average thermal emissivity coefficient E ≥ 0.90 across the infrared spectrum 2.5-30.0 µm and has an average solar reflectivity coefficient R ≥ 0.90 and/or an average solar absorptivity coefficient A ≤ 0.10 across the solar spectrum 0.3-2.5 µm.
